1. A method for dynamic access point (AP) selection by a coordinator in a coordinated AP group, the method comprising:
receiving, by the coordinator of the coordinated AP group, one or more link quality metrics for each pairing between a station (STA) and each of a plurality of member APs in the coordinated AP group, from the plurality of member APs, the one or more link quality metrics comprising at least a channel capacity between a respective member AP and the coordinator;
selecting, by the coordinator, a first anchor AP for the STA from the plurality of member APs based on the one or more link quality metrics for each pairing, the first anchor AP being used to relay downlink transmissions from the coordinator to the STA; and
receiving an uplink transmission at the coordinator, from the STA, via a second anchor AP selected by the STA from among the plurality of member APs, to be used to relay uplink transmissions from the STA to the coordinator,
wherein authentication of the STA with the first anchor AP is shared with all APs in the coordinated AP group, allowing the coordinator to utilize any subsequently selected anchor AP to relay downlink transmissions from the coordinator to the STA without re-authentication.
